A Czech fairy tale about a princess named Lada who runs away from home in a mouse fur disguise in order to escape an unwanted and forced marriage.

A poor miner, Kuba Dařbuján, cares for his wife Markýtka and eleven children. When a newborn arrives, he seeks a godfather and, finding only Death fair to all, accepts a pact: as a doctor whom Death accompanies at the foot of a patient’s bed, he can heal; but if Death stands at the head, no cure is possible. Kuba eventually heals even a miserly brewer, violating the pact and imprisoning Death, leading to a world where no one can die and unforeseen chaos follows.

It's very human and nice story about lofty princess (her father is amiable but incapable - unforgettable performance of S. Neumann) and good, nice, kind and well-principled young king (prince) who tries to make tender her calm heart to get married with her. After being refused (she's very capricious), he conclude to make her better. He start to work as a gardener at her castle (in secret) and successively bring she to her senses...The story continues when already reformed princess and the young king (she learn about his real identity later) have to take refuge from troops, that princess father (old king) has sent (of course he took a bad and mean counsellors advice). They have to take shelter by several ordinary and poor families, which are always very friendly and give them a help... Of course the tale has happy end.
